Thermal insulating products for building equipment and industrial installations - Determination of water vapour transmission properties of preformed pipe insulation

This document specifies the equipment and procedure for determining the water vapour transmission properties in the steady state under specified test conditions for test specimens of preformed pipe insulation. It is applicable to thermal insulating products.It is intended to be used for homogeneous materials (see NOTE below) and for products which can have integral skins or adhered facings of some different material.NOTE      A material is considered to be homogeneous in terms of mass distribution if its density is approximately the same throughout, i.e. if the measured density values are close to its mean density.

Thermal insulating products for building equipment and industrial installations - Determination of water vapour transmission properties of preformed pipe insulation

Le présent document spécifie les équipements nécessaires et les procédures à suivre pour déterminer à l'équilibre et dans des conditions d'essai spécifiques, les propriétés de transmission de la vapeur d'eau d'éprouvettes constituées de coquilles isolantes préformées. Il s'applique aux produits isolants thermiques. Il est destiné aux matériaux homogènes et aux produits qui pourraient posséder des revêtements intégrés ou des parements collés faits d'un autre matériau. Si la coquille isolante est découpée dans un produit plat, les propriétés de transmission de la vapeur d'eau peuvent être déterminées à partir d'essais effectués selon l'EN 12086 sur le produit plat possédant des propriétés semblables.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
